1 Water has its greatest density at 4° C. and 760 millimeter pressure. At this density, 1 liter of water 

 weighs 0.999975 kilogram. This value was used in the conversion here presented. For all practical 

 forestry purposes, a liter of water can be considered as weighing 1 kilogram. Similarly, 0.001 cubic foot of 

 water is considered as weighing 1 ounce. This density is attained at 16.7°C. 



2 Metric ton = l. 1023112 short tons.
